To all whom 'it may concern:

Be ityknown that l. Gvs'raviis A. Bamm, a citizen of the United States, residing at Chicago, in the .county of Cook and State of Illinois.v have Vinvented a certain new. and useful` Improvement in Motor-Controllers, of which the followingr is a specification.

.This inventionrelates to controlling' devicesfor gas, gasolene or other internal :co bustionengines, and has. for its object to provide a new and improved device of this description.

The inrentin is illustrated in the accom- Figure 1 is'a View iii part diagrammatic showing' one forni of construction.embodyine; the' invention; Fig. 2 is a. sectional -view-fA taken' on line 2-2 of Fig'.- L: Fie. 31s a sectional View taken on line 3--3 ofy Fig. 1.

Like numerals refer to like out. the several figures.1J

, I have shown the intention asapplied"to'- an engine havingr a constant speed; and a variable load. The shaft 1 of the engineis. provided with a fly-wheel 2. Mounted uponthe shaft v1 is ,a disk 3 having .a receiving f i recess 4 having the inclined face 5. -A' prof jection 6 is fastened to the hub or som'e other A part of thetiy-wheel. and'is adapted to project more or less into this receivingr recess,

the Vdistance Varying with the conditions.4

This projection is also provided withf a 'bereled or inc lined face4 7. which engages the beveled or inclinedface 5 on the disk. This disk is 'provided with an electrical Contact 8, which is insulated from the remaining portion of the disk in any desired manner,

and which is connected' in an electrical 'circuit preferably by beine' connected to the shaft 1 and thence to the frame `of the niachine as shown in Fig; f2. v'

The pivoted governorarni 9 is pivoted to the fly-wheel and isconnected with a spring' 10, There, ofcoprse. may be two ofthese arrns as in the ordinary governor. but` 'I have shown one in -ordcr to simplify the drawing. The arm fil provided with the ladjustable weight 11, and connected by a connectingY piece 12. with the. disk 3 (see Fig. 8), the connection being? such that `when the end of the arm 9 moves outwardly as the speed of theI {1y-wheel increases. the

dskB will he rocked lizvit-he shaft l as to.

change the position of the contact S'With relation to the stationary sliding contact 13, which engages the periphery of the disk 3.

Parts tlirough l This stationary contact is connected to the supporting piece 14.

The contacts 8 and 13 are connected in a circuitwith.; the ignition .system which ignites thematerial inthe cylinder ofthe engine. As the disk 3 isroclted by the movement of the arms J and. '12 -in opposition to the spring 10, the contact 8 ismoved so as :to 'reach the contact 13 at a later period with relation to the revolution ofthe disk and the' position ot' the piston. The hub of the disk 3 .is provided with a groove 15 in which work the pins 1G fastened to the arm :of .the hiturcated lever li' pivoted at; 1S to thetixed part.. The lever 17 is connected with the magnetic core 1.) of the coil or .so-

engine. As illustrated. this circuit is .shown as an incandescent light circuit where the kept. substantially constant lto supply the 'constant voltage necessary in such an electric in.

are as follows:-\Vl1en the engine is in 'operation. the disk 3 is rotated with the ilywheel and the contacts S and 13 are brought `together cach revolution. These contacts are so'posit'ioned as to cause the spark in tlie cylinder to be produced at the desired point of the stroke. lf now the speed of the engine increases above the desired constant speed.' the disk 3 is rockedso as to move the contact S toa position where -itengages the .contact llater in each revolution. rThis causes an ignition of the material in the cylinder later in the stroke of the piston, that,

the piston comes near to the. end of the stroke. This reduces the power of the en- `gine 'and` tends to bring the, speed back to the spring 10 is brought back and the disk -.-lenoid 20. located in an electric circuit 2S 'supplied by the dynamo 21 operated by the The corelt) of magnetic-.ma-VA connected byf'afpieeclQQywith. the

load of the dynamo is continually varying, .and where'the'.specd'of4 thedynarno mustI be which extends into lthe .coil QO isi-'of non- The nse'and operation of my invention' is, when the ignition'does not occur until A lll.

normal whereupon tl1e"arm 9 by means of v 3 rocked to change the position of the spark back to Athat at which it occurs at normal speed. If, however, the lengine is driving a variable load, such regulation is not sii'lii. cient, because when the' load is increased the speedwill vdecrease and vice versa, and I' have shown means for p'reventin this condition. If, for example, the loa increases the coil 20. moves the core 19 inwardly and rocks the valve 24 so'as to open'widerthe passageway from thel source of power sup- ,ply to the cylinderof the engine, thus percause tie spark to occur earlier, thus making it able to take care of Athe additional power uidgupply, and secure'the proper increasein er. 'If the load ,is decreased, the currentinthe:l coil 20 is decreased,fthu sl` weakening the pull upon the core 19, and

ermitting it to move outwardly under the influence of the spring 27. This moves the -of the powerl fluid, an

valve 24 to shut oi a (portion ofthe supply decreases the power of the engine.' i l? It will thus be seen that I ,have here a regulating device `lby means l.of ywhich .the
